Information collection method, device and equipment of anonymous function and readable storage medium

Abstract

The invention discloses an information collection method, device and equipment of an anonymous function and a readable storage medium, and relates to the field of program design. The method comprises the following steps: acquiring a byte code file, wherein the byte code file comprises a guide function and a byte code constant pool; function information of the anonymous function is obtained from the byte code constant pool, and a first corresponding relation between the constant pool index and the function information is obtained; obtaining a dynamic byte code instruction; interface information corresponding to the interface information descriptor is obtained from a byte code constant pool, and a second corresponding relation between the attribute table index and the interface information is obtained; and combining the first corresponding relationship with the second corresponding relationship to obtain information of the anonymous function. According to the method, function information is obtained from a byte code constant pool through a guide function, interface information is obtained from the byte code constant pool through a dynamic byte code instruction, and a corresponding relation is established between the function information and the interface information through a constant pool index and an attribute table index, so that context information of an anonymous function of a Lambda expression is obtained.

Description

technical field [0001] The embodiments of the present application relate to the field of program design, and in particular to an anonymous function information acquisition method, device, device, and readable storage medium. Background technique [0002] An anonymous function is a form of function that can be passed in without an explicit definition. The anonymous function contains an expression in the application process. In this expression, there is no need to define the name of the anonymous function, but directly use the anonymous A function expression assigns an anonymous function to a variable to realize the function of the anonymous function. Schematically, the anonymous function expression includes a Lambda expression. [0003] In related technologies, the interface for realizing click monitoring in Android development is taken as an example for illustration. Usually, the interface for clicking monitoring is implemented based on an anonymous inner class. The anonymou...

Problems solved by technology

[0004] However, when it is necessary to implement the above-mentioned click-monitoring interface through Lambda expressions, because in the Lambda expression, the interface class name and function name are both unknown and cannot be directly identified, so the above-mentioned click-monitoring interface cannot be implemented
